Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504028, here are decompositions:

67 + 31503961 = 31504028
97 + 31503931 = 31504028
181 + 31503847 = 31504028
229 + 31503799 = 31504028
277 + 31503751 = 31504028
397 + 31503631 = 31504028
499 + 31503529 = 31504028
691 + 31503337 = 31504028

Showing the first eight; more decompositions exist.
